Uploads should be sent to `/new?name={original filename}` as a POST request. If the server uses upload keys, it should be sent to `/new?name={original filename}&key={upload key}`. The uploaded file's content should be sent as raw binary in the request body.
|
||||
|
||||
Additionally, you may specify `&lastfor={time in seconds}` to make your upload temporary, or `&keepexif=true` to tell the server not to clear EXIF data on image uploads. (if you don't know what EXIF data is, just leave it as default. you'll know if you need it)

Here's an example ShareX configuration for it (with a key):
